Description

Technical Field

[0001] This utility model relates to the field of smokeless barbecue technology, specifically to a smokeless multi-mode barbecue grill. Background Technology

[0002] Barbecues are becoming increasingly popular, but traditional charcoal grilling has many drawbacks. The thick smoke produced during the grilling process not only pollutes the air but also affects human health. To solve the smoke problem, people are using electric infrared grills. The structure of an electric infrared grill consists of heating elements at the bottom and a grilling rack at the top, where food is placed for heating. While infrared grilling has many advantages over traditional grilling, during the grilling process, grease and other substances drip onto the high-temperature grill body or heating elements, vaporizing and decomposing to produce a large amount of smoke. This not only dampens the enjoyment of barbecue gatherings but, more importantly, poses a significant threat to human health and the environment.

[0003] The prior art discloses patent application number 201810531855.5, which specifically relates to a smokeless barbecue grill. This smokeless barbecue grill includes a grill body with an inner liner that has a high heat radiation reflectivity. A grilling cavity is located at the top of the inner liner, and a heating device is located at the bottom of the grilling cavity. The grilling cavity has an inverted trapezoidal cross-section, with a higher center and lower perimeter at the bottom. An oil drain port is located on the bottom side wall of the grilling cavity. The heating device includes a heating element containing a U-shaped heating tube and filled with heat-conducting oil. A sliding oil collection tray is located at the bottom of the grill body, and the oil drain port is connected to the oil collection tray via an oil guide pipe. Although this device produces no smoke during grilling and heats evenly, resulting in high-quality grilled food, its complex structure and the fact that the liquid temperature sensor and temperature control switch are prone to damage during use make it inconvenient to operate.

[0035] The heat inside the combustion rack 11 is concentrated inside the simmering zone 14. The circulating air carries the heat from the simmering zone 14 out of the combustion rack 11 through the air inlet 18 and the vent 16. The hot air flowing out of the combustion rack 11 grills the food on the grill plate 22. At the same time, the smoke inside the combustion rack 11 is mainly concentrated inside the simmering zone 14, with a small amount of hot air flowing out of the simmering zone 14 to grill the food. This enables the grill to achieve a smokeless mode. Meanwhile, the heat insulation plate 13 and the cover plate 27 located on top of the bottom plate 12 can reduce heat loss.
